Abstract

The invention relates to agriculture and provides increased separation efficiency as well as increased productivity. Above the inclined filtering plane 4 there is installed a preliminary dewatering means, made in the form of a curved perforated surface 2, and a hollow chamber 3 located inside it. Liquid manure from the nozzle enters the cavity from surface 2 and chamber 3, where it is dehydrated. The liquid fraction enters collection 5. The condensed fraction is further dehydrated on plane 4 and enters the solid fraction receiver 6. Conjugation of chamber 3 with the free wall of feed unit 1 creates a cavity with increased pressure and increases the residence time of manure on the perforated surface. 1 hp ff, 1 ill.

(54) INSTALLATION FOR SEPARATION OF LIQUID MANure INTO FRACTIONS (57) The invention relates to agriculture and provides increased separation efficiency, as well as increased productivity. Above the inclined filter plane 4, a preliminary dewatering device is installed, made in the form of a curved perforated surface 2 and a hollow chamber 3 located inside it. Liquid manure from the nozzle enters the cavity from the surface 2 and chamber 3, where it is dehydrated. The liquid fraction enters the collection 5. The thickened fraction is additionally dehydrated on the plane 4 and enters the receiver 6 of the solid fraction. The coupling of the chamber 3 with the free wall of the feed unit 1 ensures the creation of a cavity with increased pressure and increases the residence time of manure on the perforated surface _Λ . 1 s.p. f-ly, 1 ill.

The invention relates to agriculture, in particular to installations for the separation of liquid manure.

The purpose of the invention is to increase the separation efficiency, as well as improving productivity.

The drawing shows a plant for the separation of manure into fractions, a General view.

The installation comprises a supply unit 1 in the form of a nozzle, at the outlet of which a preliminary dewatering means is installed, made in the form of a curved perforated surface 2 and a hollow chamber 3 located inside it. The input surface 2 is connected to one of the walls of the supply unit 1. Under the inclined filtering plane 4 there is a liquid collector 5 and a solid fraction receiver 6. The hollow chamber 3 is associated with the free wall of the supply unit 1. The chamber 3 is in communication with the collector 5 of the liquid fraction, and the upper portion of the wall of the chamber 3 is perforated. The output section of the curved perforated surface 2 is associated with an inclined filter plane 4. The casing 7 covers the perforated surface 2 and the plane 4.

Installation works as follows.

The initial manure through the feed pipe enters the nozzle and then enters the cavity formed by a curved perforated surface 2 and a hollow chamber 3, one of the sections of which is perforated. Liquid manure, due to the acceleration obtained when exiting the nozzle, striving to move in a straight line, gets to surface 2, the liquid fraction passes through the perforation of surface 2 and enters the cavity bounded from above by the protective casing 7. Part of the liquid manure is reflected from the surface, falls on the chamber perforation 3.

Here the filtering of the latter takes place. The liquid fraction, having passed through the perforation of chamber 3, enters its continuous part and is discharged directly into the collector ₅ 5 of the liquid fraction. The solid fraction isolated on the perforation of surfaces 2 and chamber 3 due to residual inertia, previously acquired by liquid manure and backwater from new portions of the latter, moves along surfaces 2 and chamber ¹⁰ 3, is additionally dehydrated, and falls onto an inclined filter plane 4: Here, the solid the fraction is finally dehydrated and enters the receiver 6 of the solid fraction. The liquid fraction 15 is collected in the collection vessel 5 and then discharged to the outside.
